How to Recover RAID 5 Data from Failed Synology NAS

I'd need to retrieve data from three RAID5 disks on a broken Synology. The previous RAID setup was a single-volume HFS RAID5. I saw that it is feasible to do this with Ubuntu. Still, I wanted to know if it was also possible to do it with a new Synology NAS, possibly of the same model as the previous one, because a new one would have to be acquired anyhow.

If you need to recover data from your 3 disks in RAID 5 on the failed Synology, you should know the causes.

Synology RAID-based NAS devices may encounter data loss due to file loss, whether intentional or unintentional, Disk startup formatting in preparation for employing NAS RAID disks, improper configuration as a result of power, and other human or system mistakes. If you experience Synology data loss due to the mentioned causes, you have two options for recovering deleted or lost files from Synology NAS disks.

Before you purchase a new device, you might consider recovering NAS data first. There will be no more RAID reconstructions or hard drive disconnections and reconnections. Simply choose your NAS device, enable SSH, and recover deleted files from NAS devices. EaseUS Data Recovery Wizard has simplified NAS data recovery. After deleting, formatting, partition loss, system crash, virus attack, or other data loss scenarios, this file recovery program can recover lost files, photographs, documents, and videos. Almost all NAS brands and file types are supported.

This thorough data recovery tool allows you to recover data from both the ext4 and btrfs file systems on your Synology NAS equipment with a few simple clicks, eliminating the need to remove numerous disks.

If the Synology data recovery has failed, but all of the drives are still operational, moving them to a new (same or similar model) will allow you to import the configuration and save the data.

"Backup and Restore" is one of the built-in Windows 10 utilities for backing up Synology NAS for Windows 7. This feature was intended for Windows 7, but it ended up in Windows 8 and, eventually, Windows 10.

Microsoft added this backup function in Windows 10 to make it easier to store files and data on local hard drives, external hard drives, the cloud, and even Synology NAS. Assume you wish to use Backup and Restore to back Windows 10 to a Synology NAS. In that case, you'll need to pick it as one of the options and then enter your network credentials, so the system can save your files automatically.

Personal files, system settings, and program files can all be backed up to Synology NAS. Aside from files and data, Backup and Restore (Windows 7) lets you produce a "System Image". This helps to recover your computer system easier if something goes wrong.
